Description
Die Erfindung betrifft Einrichtungen und Verfahren entsprechend dem Ober
begriff des Anspruch 1.
Damit Diesel- oder Otto-Motoren einen höheren Wirkungsgrad erzielen, sollte
die die Umwelt belastende Abfallwärme (über 50%, der aufgewendeten Energie)
wenigstens teilweise zurückgewonnen werden.
Es ist bekannt, wie auch in DE 30 30 289 ausgeführt, daß Verbrennungsmotoren
systembedingt, nach jedem Kaltstart, besonders bei nachfolgendem "stop and
go"-Verkehr, unverhältnismäßig hohe Kraftstoffverbräuche mit extremen
Schadstoffemissionen haben.
Zusätzlich werden durch normale Auslaßkrümmer am Motor mehr als 50% der
eingesetzten Energie ungenutzt als Wärmeumweltbelastung abgeführt!
Hochleistungs-Fächerrohrkrümmer - in Zeolithe eingebettet - mit einem
Schutzgehäuse (Fig. 1) umgeben, verringern die Wärmeabstrahlung deutlich, weil
Zeolithe ein guter Wärmeisolater plus Latentwärmespeicher ist.
Der nachfolgende Katalysator erreicht dadurch auch seine Starttemperatur für die
katalytische Abgasreinigung schneller.
Da Hochleistungs-Fächerkrümmer im Vergleich zu Gußkrümmern oder
Gußkollektoren bereits eine Wirkungsgradverbesserung bringen, kann diese
Eigenschaft noch nachhaltlich optimiert werden, mit der bekannten
Latentwärmespeichermöglichkeit von Brennkraftmaschinen
Die ungenügend langen Desorptionszyklen bei bekannten Zeolith-Latentwärme
speichern werden durch die Kombination mit einen Hochleistungs-
Fächerkrümmer weiter verbessert.
